1760 Empress Catherine, the Great with her husband Peter III of Russia and their son, future Tsar Paul I of Russia by ? (location unknown to gogm)

Young Grand Duke (future Tsar) Paul poses with his mother Catherine and nominal father Peter in this portrait; Paul's paternity is uncertain. Genetically, Elizabeth was the last Romanov ruler and the subsequent Romanov Tsars were the result of marriages between Romanovs and Germans, if Paul was the offspring from Catherine's affair with Sergei Vasil'evich Saltykov, until Alexander III married a Danish girl, Dagmar Glucksberg. If Paul was actually Catherine and Peter III's genetic child, then Paul was genetically all German and the following Romanov Tsars were all German other than Nicholas II who was half Danish.
